In 2009 AppliedMicro changed their branding from AMCC to AppliedMicro, but still retain the name "Applied Micro Circuits Corporation" officially.

In 2011, AppliedMicro became the first company to implement the ARMv8-A architecture with its X-Gene Platform. In November 2012 at ARM TechCon, AppliedMicro demonstrated advanced web search capabilities and the ability to handle big data workloads in an Apache Hadoop software environment with the X-Gene Platform using FPGA emulation. A silicon implementation of X-Gene was first exhibited publicly in June 2013.[3]

AppliedMicro has a sponsor level membership of Power.org and is one of the original members. AppliedMicro is also executive member (Chairman position) of the Ethernet Alliance. AppliedMicro is also a member of the Open Compute Project.

The Processor Products group designs and markets embedded microcontrollers as well as server processor, packet and storage processors. It includes the network processors of former MMC Networks (acquired October 2000) with IBM PowerPC 4xx series microcontrollers (acquired April 2004).

Since purchasing the IBM PowerPC 400 family (under the 405 and 440 series product names), AppliedMicro has developed the 460 series with 440 CPU, and a multicore Power architecture devices.

In January 2008, the AppliedMicro PowerPC 405EX was awarded PRODUCT OF THE YEAR 2007, by Electronic Product Magazine.

Also in January 2008, AppliedMicro announced an extension of its relationship with IBM Semiconductor; IBM now incorporates the AppliedMicro PowerPC 4xx product line in its Semiconductor Solutions offering. Under this expanded relationship, AppliedMicro and IBM’s Semiconductor Solutions sales forces both market AppliedMicro's PowerPC 4xx products. AppliedMicro has added customers like Accusys and Qlogic to its large customer base for its PowerPC product line.

In October 2011, AppliedMicro announced its X-Gene Platform, an ARM 64-bit solution aimed at cloud and enterprise servers.

In 2005, the company paid $60 million to settle a class-action lawsuit on behalf of investors against the company and certain of its current and former officers and directors.[5] The suit had charged the company with issuing a series of materially false and misleading statements concerning the company's operations and prospects for Q4 2001 and beyond.[6] Under the terms of the settlement, the company and defendants denied any wrongdoing. About half of the amount of the settlement was covered by insurance.[5]
